DEVICE-FORT-THROWING HEAVY BELTS UPONYI PULLEYS.

SPECIFICATION forming part of Letters .Patent No. 692,833, dated February 1 1, 1 902.

Application filed July 8, 1901.

To all whom it may concern: I

Be it known that I, TRUMAN A. On0WNER,a

citizen of the United States,residing at Wil na,

in the county of J efie'rson and State of New York, have invented a new and useful Device for'Adjusting Heavy Belts upon Pulleys, of which the following is a specification.

My invention relates to a safe andconvenient device for throwing heavy belts upon pulleys by a single operator without crimping or splitting the belt through the center. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a view in perspective of the 'entire device. Fig. 2 shows in perspective that portion of the device known asan adjustable hinged clamp. Fig. 3 shows in perspective the main clamping-bar over which the belt is thrown and which is clamped to the rim of the pulley by the clamp shown in Fig. 2. Fig. 4 shows the iron band by means of which the clamp is held in place. Similar letters refer to similar parts throughout the several views. I

A is an iron or steel clamping-bar, varying in length according to the size of the belt and pulley, one end being recurved, so as to form a hook to engage the rim of the pulley.

B and D are partsof a clamp, hinged at E and secured to the clamping-bar by means of the thumb-screw C, passing through the slot F in the said bar, allowing that portion of the clamp D to be secured at different points on the lever A and so adjusted to different-sized rims. D has a boss 12 on its under side, which moves in the slot F in the leverAand serves to guide the clamp as it moves on the bar.

When the part D is clamped to the bar by the thumb-screw O, the hinge atE allows the clamping-jaw B to be moved upon the pivot from side to side. The clamping-bar is at- Serlal No. 67,470. (N0v model.)

tached to the rim of the pulley by pushing,v

the movable portion of the clamp B to one side,

hooking the end of the bar A over one edge of the rim,and shoving the'part B ofithe clamp over the other edge of the rim and securing it in place by shoving thebandm into place,

asshowninFig.1. ThejawBismadeslightly i thrown into place on the pulley when the s belt-adjuster maybe removed by sliding the band an back toward D, past the hinge'E, and

.turning the jaw B to one side on its pivot.

'What I claim as my invention is-' 1. The improved belt-adjuster, herein set forth, the same comprising the clamping-bar, provided with a permanent terminal hook and an independent clamping-jaw adj ustablymounted upon said bar, and having means for lateral swinging thereupon, whereby the belt-adjuster may be quickly engaged with and disengaged from a belt-pulley of any width as set forth.

2. The improved belt-adjuster herein set forth, the same comprising the clamping-bar A, provided with a permanent terminal hook, the independent clamping-jaw B, vertically pivoted to the block D, said block being mounted to slide upon theclamping-bar and The ,beltis then thrown over the bar provided with means for locking said block to said bar at forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
